5 E461754
2.3.1. Settings menu for CLM1000-Professional
Through the simultaneous pressing of the two arrows for about 2
seconds, the setting menu of CLM1000-Professional will appear.
The various menu items can be selected using the arrow keys.
With "EXIT" the setting menu will be closed.
Start a new measurement
If the OK button is pressed for the shown setting, then all
measured values and the measurement times will be set to zero
and the device starts a new measurement! The CLM1000 changes
to item 5 (10).
(The consumer that needs to be measured should already be
switched on)
Set up of the ON%-Threshold (Standby Mode)
If the OK button is pressed for the shown setting, then you can use
the arrow keys to adjust the threshold for the "ON%" calculation.
This threshold can be from 0 Watts to 100 Watts.
An accurate description of this function can be seen under:
"2.3.3 Description of the" ON% "
Set up the display color for different values
If the OK button is pressed for the sh
own setting, then the Settings
menu for the Colour-Setup will be displayed.
Here, the thresholds for the red, yellow and green colours can be
set.
For the example in the left, the colour modification of the display is
enabled and the display lights up:
green when power is bigger than 5 watts
yellow when power is bigger than 10 watt
r
ed when power is bigger than 20 watt
Caution: The colour c
hange function is valid only for the Menu

Setup of the interface and of the data logger (only Plus-Version)
If the OK button is pressed for the shown setting, then the interface
and the data logger menu appears on the display.
The individual menu items can be selected by using the arrow keys
and the settings can be applied by pressing the OK button.
Baud rate: The transfer speed can be here adjusted (9600,
18200, 38400, 57600, 115200) Baud.
When exiting this menu, the transfer speed will be
set up and stored.
Save rate: The storage rate for internal memory can be chosen
here. (1, 5, 10, 30, 60 seconds)
Size: Available storage space depends on the current
storage rate.
1 Second: 24 hours
5 Seconds: 5 days etc.
Send data: Once activated the device sends all the
measurement data previously “Log data” saved with
and deactivates the menu point automatically after
the after the successful data transmission.
Log data: If this menu item is activated, CLM1000 will save the
measurement data in the internal memory.
Attention: Starting a new data storage means that
the previously recorded data will be deleted.
Send CSV:
The current measured data is continuously
transmitted with the adjusted speed and storage
rate. Deactivate this setting to stop the
transmission.
Setup the date and time setting (only Plus-Version)
If the OK button is pressed for the shown setting, then the time
and date can be adjusted.
The settings remain stored even after you turn off the device.
The summer and winter time switch is not automatic.

2.3.3. Description of the ON% Function
Many consumers (e.g. refrigerator) doesn’t need constantly the full power from the
supply! Therefore it is interesting to know for how long a consumer really needs the full
power, and not only for how long it runs on Stand-by Mode.
The function "ON%" indicates how much of the entire measurement time and for how
many hours does the consumer run in the adjusted ON threshold (Stand-by Mode). The
following diagram illustrates the measurement principle.

3. Interface (only Plus-Version)
USB-Interface:
The measuring instrument CLM1000 has a USB- interface. The
current measuring data and the stored data can be transferred
cyclically in the CSV- mode. In addition, the provided transmission
cable can be used.
The CLM1000 uses internally a USB-RS232 converter.
After the successful installation of the WINCLM program, the interface of
the CLM1000 is recognized and can be used as COM Port on your
computer.
Transfer format:
1 bit Start, 8 bit Data, 1 bit Stop, without parity
Transfer rate:
Depending on the setting:
• 9600 Baud
• 18200 Baud
• 38400 Baud
• 57600 Baud
• 115200 Baud
Since the transmission rate of the measuring instrument is limited to
115200 Baud, the transmission time of the internal data memory on
the computer could take some minutes.

Visualising
Software:
The current and the stored measuring data can be stored, analyzed and
visualized in the CSV- format with the visualising tool WINCLM. The
stored * csv file can be opened and processed with the usual spread-
sheet programs.
Example visualization WINCLM:
The WINCLM software and the software description can be downloaded
from the homepage of Christ-Elektronik GmbH.
www.christ-elektronik.de
(Product Range of Measuring Instruments)
Important pointer:
The software WINCLM will no longer be supported. See chapter 7
"Software and data evaluation" for further information about other
software and about the data evaluation.

4. Error handling
The CLM1000 gives users warning of internal errors which
occurred!
If there is an error the display is red and displays the occurred
error!
Error Meaning Solution
ERROR1
Internal error 1!
CLM1000 doesn’t start!
Unplug the CLM1000 and plug it
again!
If the error continues to exist
the CLM1000 can’t be used.
!Please send in!
ERROR2
Internal error 2!
The CLM1000 shows the error
and all readings are reset.
The CLM1000 starts a new
measuring!
If this error keeps occurring
during start-up the CLM1000 has
to be sent in for further
inspection.
ERROR3
Amperage above the maximum
allowable value (more than 16
Ampere)
Unplug wattmeter!
ERROR4
The internal memory doesn’t
work.
If this error keeps occurring
during start-up the CLM1000 has
to be sent in for further
inspection.

6. FAQ
Question 1:
The displayed current varies between 0 mA and 3 mA?
Answer 1:
The measured current almost corresponds to the one of the no-load operation's
detection. As a result the displayed value varies between 0 mA (no-load operation
detection) and the minimum measurable current of 2 mA. Consider the tolerance of +- 3
mA too.
Question 2:
My measuring instrument doesn't display any measuring values, although at least a 3
mA current runs.
Answer 2:
A current exceeding 3 mA may run through instruments having only an inductive or a
capacitive load and no measured value would be displayed. Reason: in the case of a low
power factor, the active power lowers under the point of no-load operation's detection
and every measured value is reset.
